 /// A multiplexing [RawReceivePort].
 ///
 /// Allows creating a number of [RawReceivePort] implementations that all send
 /// messages through the same real `RawReceivePort`.
 ///
 /// This allows reducing the number of receive ports created, but adds an
 /// overhead to each message.
 /// If a library creates many short-lived receive ports, multiplexing might be
 /// faster.
 ///
 /// To use multiplexing receive ports, create and store a
 /// [RawReceivePortMultiplexer], and create receive ports by calling
 /// `multiplexer.createRawReceivePort(handler)` where you would otherwise
 /// write `new RawReceivePort(handler)`.
 ///
 /// Remember to [close] the multiplexer when it is no longer needed.
-/// `
+///
 /// (TODO: Check if it really is faster - creating a receive port requires a
 /// global mutex, so it may be a bottleneck, but it's not clear how slow it is).
